There have been many inquiries regarding the annoying Tachometer / Revolution Counter chattering and malfunction. Over the past two weeks I worked up enough courage to dive under the dash, into the foot well, and remove my tachometer, and I shipped it off to Rick Borth, at Overseas Speedometer. I reinstalled it yesterday afternoon, and what a great result. No noise, smooth function, without the needle jumping. Turnover time was just over a week, and charge of $85 plus tax and shipping. Priceless.....
